I have a good pc, and a 17" Samsung LCD Monitor.... it's always been fine until I changed recently to a larger hard drive.. Now, when I open photos, webpages, etc everything looks great.. BUT when I open photos with my PS CS or my Nikon picture project, they look extremly Dark!! Its so hard to work on these photos with these conditions.. Any ideas?? this is what I see when i use the standard Preview And the same pic when I open it with a image editor.. uggggggggggggg! help? Thanks!
